12b16077c4 lib/storage: reset MetricName->TSID cache after deleting time series
This should prevent from adding new data points to deleted time series
without the need to check for the deleted time series.

This improves ingestion performance a bit when the `deleted time series ids` aka `dmis` set
contains big number of time series.

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/596

Based on the idea from @n4mine at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/604

6daa5f7500 lib/storage: prioritize data ingestion over heavy queries
Heavy queries could result in the lack of CPU resources for processing the current data ingestion stream.
Prevent this by delaying queries' execution until free resources are available for data ingestion.

Expose `vm_search_delays_total` metric, which may be used in for alerting when there is no enough CPU resources
for data ingestion and/or for executing heavy queries.

app/vmalert: add retries to remotewrite (#605)
* app/vmalert: add retries to remotewrite

Remotewrite pkg now does limited number of retries if write request failed.
This suppose to make vmalert state persisting more reliable.

New metrics were added to remotewrite in order to track rows/bytes sent/dropped.

defaultFlushInterval was increased from 1s to 5s for sanity reasons.

app/vmalert: support multiple notifier urls (#584) (#590)
* app/vmalert: support multiple notifier urls (#584)

User now can set multiple notifier URLs in the same fashion
as for other vmutils (e.g. vmagent). The same is correct for
TLS setting for every configured URL. Alerts sending is done
in sequential way for respecting the specified URLs order.

* app/vmalert: add basicAuth support for notifier client (#585)

The change adds possibility to set basicAuth creds for notifier
client in the same fasion as for remote write/read and datasource.

deployment/docker: replace Prometheus with vmagent (#589)
vmagent replaces Prometheus to perform scrapes and writes
into VictoriaMetrics installation. Prometheus datasource was
dropped, but its config was reused to feed vmagent.

Change also contains simplification in dashboard propagation
to Grafana container by removing excessive json manipulation
steps.

vmselect: fix label_replace when mismatch (#579)
As per documentation on `label_replace` function: "If the regular
expression doesn't match then the timeseries is returned unchanged".

Currently this behavior is not enforced, if a regexp on an existing
tag doesn't match then the tag value is copied as-is in the destination
tag. This fix first checks that the regular expression matches the
source tag before applying anything.

Given the current implementation, this fix also changes the behavior
of the **MetricsQL** `label_transform` function which does not
document this behavior at the moment.

7209d58fbd app/vmselect/netstorage: increase concurrency when processing small number of time series with big number of data points per each time series
Previously VictoriaMetrics was processing up to 32 time series in a single goroutine.
This could be slow if each time series contains big number of data points (10M+ or more), since only a single CPU core could be loaded with work,
while other CPU cores were idle. Fix this by launching GOMAXPROCS workers for time series processing.

This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/572

2a39ba639d lib/promrelabel: add support for keep_if_equal and drop_if_equal actions to relabel configs
These actions may be useful for filtering out unneeded targets and/or metrics if they contain equal label values.
For example, the following rule would leave the target only if __meta_kubernetes_annotation_prometheus_io_port
equals __meta_kubernetes_pod_container_port_number:

  - action: keep_if_equal
    source_labels: [__meta_kubernetes_annotation_prometheus_io_port, __meta_kubernetes_pod_container_port_number]
